Web 2.0 is a general term given to the user experiences of the World Wide Web during the first part of the 21st Century. Key elements that define Web 2.0 is the ability for the user to engage and interact not only with content on the web, but with other users of the web. Users are allowed to share and receive information, experiences and collaborate.
Where the original "Web 1.0" allowed only for retrieval of information, Web 2.0 is seen as a participatory medium. Consumers of information can also be seen as creators of information.
Origin
The term "Web 2.0" is largely credited to Tim O'Reilly of O'Reilly media.
Examples
Blogging - Blogging allows for a person to share their personal thoughts and for other users to make comments. Blogging can be considered a sort of online journal. These thoughts are formed in "posts" and can be "tagged" with keywords that are relevant to the topic presented in the post.
Wikis - Acting more as an information repository where users are allowed to edit static content. Used mainly as "How to's" or useful information that changes infrequently. Wikipedia is the largest and most well know example. Wikispaces allows anyone to start their own wiki and invite others to collaborate.
Podcasts - The radio medium brought to the internet, but also allows anyone to upload and share vocal recordings. Podcast Alley, Podcast Bunker, and Podcast.com are three popular sites listing top podcasts.
Video capture - Allows users to generate, upload, and view videos. YouTube and Vimeo are two popular video sites.
Controversy

*The terms "new new media" and "social media" overlap with the term "web 2.0"
